Description edA-qa mort-ora-y 2016-06-12 12:35:35 UTC 
The calculation of text height is broken again. This is a regression of bug https://bugs.kde.org/show_bug.cgi?id=322765

I have this text:
trace( bit_shl｢binary 32bit｣( 1, 10 ) )

And in the two screenshots you can see it clipped in one and not the other. Deja Vu Sans, and several Serif fonts work, though some with large line spacing. LIberation Sans is what I used before (it worked in previous versions, as did most fonts after the linked issue was fixed before).

This is a major regression as it basically makes Unicode characters unusable in Kate -- except for some select fonts where they still do.

Reproducible: Always

Steps to Reproduce:
1. Type Text: trace( bit_shl｢binary 32bit｣( 1, 10 ) )
2. Add lines around it
3. See clipped text

Known issue, but there is no fix yet. Would be cool if someone with better knowledge in these languages would find time to look into this.
